To ALL- WIIoMrr 'MAY ooNoERN: k

- Beit knownpthat I, L. F. BROWN, of the city of Keokuk, county of Lee, and State of Iowa, have invented a new'and useful Improvement in Gates; and I do hereby declare the followingV to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters ofref'erence marked thereon, in which- Figure 1 4is a perspective elevation of luy improved gate, and

Figure 2, sheet 2, is a ground plan, showing the different parts of the same.

The object of this invention' is to form a gate which can be opened or closed by a person approaching from either side, before reaching the gate.

This improvement consists in agate, and the apparatus for operating it, which is made as shown in the drawings', and as hereinafter set forth, using several well-known parts, which canbe more or less varied, as desired.

"Two sills A A are laid parallel on the ground, a small distance apart, whichjoin at each end a cross-sill, D D. The cross-sills D D' 'extend out in different directions, a's shown, parallel to the roadway across which the gate is made; At or betwecn the ends of the sills AA are posts C C', which are made donb'le, to allow the panels of the gate t'o be held, and to pass between them for opening and closing. At the out ends of sills D D' are hollow posts, E E', which at their tops contain cross-cylinders'xed on journals that turn in the posts, and have the handcranks F F at their ends', which the person who Wants to open the gate can turn for that purpose without dis- 'mounting, if riding. At the feet of posts E E' are two pulleys, I-I I, II' I', each turning freely, and near the posts C C'iare two more pulleys each, K K'. Between the sills Al A','at each end, are cross-cylinders G G', also turning freely, and in line between the two pairs of pulleys K K'. Now, asrope, L, passes around the cylinder at crank F one or more times, so as to be given'oi or taken up by turning crank F either way. This ropeL passes Vdown inside of post E and over pulley H, thcnce'over one of pulleys K, and around cylinder Gr one or more times, to insure its turning by the rope,-thence over one of the pulleys K', over pulley I-I, and up post E' to and around'cylinder at once' or more times, for the same `purposeas around that at F, whence passing down `ngain as rope L it passes over pulley I', the other pulley at K', around the cylinder G once or more times, as

at G, over the other pulley at K, and pulley I to the beginning, thus forming an endless cord or belt, arranged for the purpose of turningthe cylinders G together in opposite directions, so as to run the two panels of the gale B B together or apart, to open or close. Under cachot' the panels B B there is a rope, M M', attached to the two ends of the panel, which ropes respectively pass around cylinders G G' one or more times, so that the turning of the cylinders will pull the panels open or'toget-her, or other arrangements of gearing can be used therefor. The framebed A A can be covered for roadway.

The cranks F F', with their cylinders, the posts E E', pulleys II II'I' I', K K', the cylinders Gr G', and rope'L L', or their substantial equivalents, combined and arrangedV as and for the purpose specified.

L. F, BROWN.
